The effect of whey protein concentrate based edible coating incorporating different concentrations of natamycin and lysozyme-xanthan gum conjugate on ultrafiltrated white cheese shelf life was investigated. Escherichia coli O157: H7 (as an indicator for gram negative bacteria), Staphylococcus aureus (as an indicator of gram-positive bacteria), and Penicillium chrysogenum (as a mold) were inocul...

GR99060 and GR99062 are representatives of a series of 1,2,4-triazino[5,6-b]indole compounds. This series possessed broad-spectrum antifungal activity in vitro. The MIC ranges of the two compounds were as follows: 0.25 to 4 micrograms/ml for Candida albicans, 0.25 to 16 micrograms/ml for Candida sp., 1 to 8 micrograms/ml for Aspergillus spp., and 0.25 to 16 micrograms/ml for Cryptococcus neofor...

BACKGROUND The relationship between male infertility and gr/gr deletions that remove multiple genes of the Y chromosome varies among countries and populations. The aim of this study was to investigate the association between gr/gr deletions and spermatogenic phenotype in fertile and infertile Japanese men. METHODS The subjects were screened by sequence-tagged site (STS) analysis to detect gr/...

The interaction between nano-SiO2 and lysozyme was investigated by the method of UV-Visible  detection and fluorescence spectroscopic techniques. The thermal denaturation of lysozyme has been investigated in the presence and absence of nano-SiO2 over the temperature range (293-373) K in different buffers and pH values, using temperature scanning spectroscopy. The presence of nano-SiO2 caused th...

Methylprednisolone (MP), a glucocorticoid, is the only effective therapeutic agent used in the clinical treatment of acute spinal cord injury (SCI). MP given within 8 hr after SCI significantly improves neurological function. Although the glucocorticoid receptor (GR) is suggested to mediate MP actions, limited knowledge is available on its expression and possible function after SCI. Presently, ...

in the present study, the interaction between nano-tio2 and lysozyme was investigated by the method of uv-vis detection and fluorescence spectroscopic techniques. the thermal denaturation of lysozyme has been investigated in the presence and absence of nano-tio2 over the temperature range (293-373) k in different buffer and ph, using temperature scanning spectroscopy. the presence of nano-tio2 ...

This study was conducted to determine the effect of lysozyme addition on in vitro rumen fermentation and to identify the lysozyme inclusion rate for abating methane (CH4) production. An in vitro ruminal fermentation technique was done using a commercial concentrate to rice straw ratio of 8:2 as substrate. The following treatments were applied wherein lysozyme was added into 1 mg dry matter subs...

Divalent copper was found to inhibit non-competitively the lysis of Micrococcus lysodeikticus cells by hen egg-white lysozyme, with an inhibition constant K, = 3.8 X lo2 M-l. The association constants of Cu2+ for lysozyme and for a derivative of lysozyme in which tryptophan residue 108 was selectively modified, were measured spectrofluorimetrically and found to be 1.8 X lo2 M-l and 1.0 X lo3 M-...

Background: To prevent or inhibit the growth of pathogenic microorganisms and food spoilage factors, many studies have been done by using natural preservatives. The aim of study was to investigate the effect of different concentrations of lysozyme and Nisin on the growth rate and also to determine the minimum inhibitory concentration (MIC) and minimum bactericidal cocentratiin (MBC) of these co...
